OBJECTIVE: The purpose of this study was to determine the function of long non-coding RNA (LncRNA) ENST00000434223 (Lnc ENST) in renal carcinoma, and to explore the potential molecular mechanism.
PATIENTS AND METHODS: Quantitative Real-Time-Polymerase Chain Reaction (qRT-PCR) was used to detect the expressions of lncRNA ENST00000434223 and Wnt/β-catenin pathway-related mRNAs in tissues and cells of renal cancer. Chi-square test was performed to figure out the relationship between lncRNA ENST00000434223 and clinic-pathologic features of renal cancer patients. Besides, si-NC, si-ENST00000434223, pcDNA-NC and pcDNA-ENST00000434223 were transfected into renal cancer cells. The proliferative ability, metastasis and invasiveness of cells were detected using Cell Counting Kit-8 (CCK-8) and transwell assay, respectively. Lastly, the activation of the Wnt/hygro-catenin signal transduction pathway was evaluated by TOP/FOP Wnt Luciferase reporter assay and Western blot.
RESULTS: The expressions of Wnt2b and β-catenin were significantly increased in renal carcinoma, while E-cadherin was markedly down-regulated. Lowly expressed ENST00000434223 was involved in the poor prognosis of patients with renal cancer. In addition, down-regulating ENST00000434223 could enhance the viability, metastasis and invasiveness of renal cancer cells. However, overexpressing ENST00000434223 remarkably weakened the above cell functions. At the same time, interference or overexpression of ENST00000434223 could affect the expression level of proteins related to the Wnt/β-catenin signal pathway.
CONCLUSIONS: LncRNA ENST00000434223 inhibits the progression of renal cancer through the Wnt/shell-catenin signal pathway.Free PDF Download
